The playable character is a neanderthal armed with a club. In a search for food, the neanderthal must hit dinosaurs and other animals that come in his way. Some hostile beings can't be beat, so the player must dodge them. A boss awaits in every even numbered level. There are seven levels.

Prehistorik received a rating of 85% from Amiga Action in August 1991, with the review stating "after playing Prehistorik for a few minutes I was not disappointed. Graphics, sound and gameplay are all outstanding. My only complaint is that the puzzle element could have been taking (sic) a little further. A must for any platform or arcade fan."
